Hi , Now we have had a debian version of musical chairs where Lenny is now the obsolete ,  Squeeze is now the stable and Wheezy is now the testing.

Here is the script to make the Wheezy rfs, plus my personal tweaks.

Code: [Select]

#Script hacked from the original Ubuntu one by Mark Gillespie (
#Version History:
#1.0 Initial Release
#1.1 Made debian build path relative, Did a check to ensure it does not go past stage 1 bootstrap on non-armv5 (sheevaplug) hardware, Reminder at end to delete debian build dir.
#1.2 small fix to arch detection.
#1.3 Added sanity check to ensure it's running under BASH, changed packages to include ssh, added some colour to the output, made ehe gziping non-verbose.
#1.4 Fix to ensure the serial console device gets created correctly.  Added an apt package listing in the root of the filesystem, added move verbose messages, removed documents and man pages from the filesystem.
#1.5 Additional Cleanup, single variable to switch between lenny and squeeze.

DIST="testing" # Comment oout this line to make a stable (squeeze) build

#before we go any further, make sure we are running BASH, not that dumb mess that calling sh and getting dash thing that Debian/Ubuntu impmented.
test -n "$BASH_VERSION" || { echo "\033[0;31mERROR:\033[0;39m This script must be run using BASH and not other shells like DASH.\nIf you launched this as 'sh ./$0', try just launching it directly './$0' (after chmoding it +x).\n"; exit 1; }

Just to get things right and understand a little bit more this thread is all about...

I have a new Dreamplug and want Debian Sqeeze on there...

Several questions:

1) I need a micro sd card, partition it to vfat (i.e. 25MB) and ext3 (i.e. rest of usd)?
2)I then copy the script into a text file? (Minor changes -> i.e. Squeeze for "testing" etc)
3) Make it executable (chmod 777)?
4) Run it with Bash in the ext3 partition (Command)?
4) Put a uImage to vfat partition (which one) ?
5) Take usd out of DreamPlug and put new one we just created in the Plug?
6) Just power on or use jtag to change anything?

Thank you guys so much for making life a little bit more simple! You rock!!

This is a Sheevaplug board. Therefore some of the details will differ, but the principle of using debootstrap should work for both.

debootstrap is a command used to build a rootfs. The script that was pasted into the comment earlier in this thread has comments. Those comments explain many things, but not necessarily everything that you might need to know.

You use the script to build a roots; at least the second part of the script must be run on a device that uses the same processor as your target device. The rootfs that you build may occupy a Gigabyte or more of disk space (if you install a desktop environment, which is not a part of this example script), so you must ensure that you will have enough free disk space for the rootfs and probably the compressed version that you create at the end.

chmod a+x scriptname to make the script runnable.

When you have created the rootfs, you transfer it to a device (ie (micro)SD card, hard drive) that must be partitioned correctly for the hardware that you are using.

For instance, the standard way of booting a Sheevaplug from SD card involves putting 2 partitions on the SD card; a small ext2 partition for the kernel and a larger ext3 partition for the rootfs. There may also be requirements for the environment variables.

The Dreamplug partitioning requires a FAT partition for the kernel and ext3 for the rootfs
